Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments of the present application and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
In the use scenario of electric vehicles, there is typically a heating demand or a cooling demand. For example, an air conditioner, which is a main vehicle component for adjusting the temperature in the cabin, may output hot air or cold air into the cabin according to the needs of a user, in which case the air conditioner has a heating demand or a cooling demand. For another example, as a power source in an electric vehicle, the charge and discharge capability of the power battery affects functions of many vehicle components in the electric vehicle, and in order to ensure normal operation of each vehicle component in the electric vehicle, it is important that the power battery exhibits its optimal charge and discharge capability. However, the charge and discharge capacity of the power battery is reduced at high or low temperatures, so maintaining the temperature of the power battery within a suitable temperature range is critical to ensure that the power battery exhibits optimal charge and discharge capacity. This requires cooling the power cell when it is above its proper temperature range and heating the power cell when it is below its proper temperature range in order for the power cell to perform best in the proper temperature range.
In the embodiment of the application, the condition that the power battery in the electric automobile needs to be heated and/or the air conditioner needs to be heated is called that the electric automobile has a heating requirement, and the condition that the power battery in the electric automobile needs to be cooled and/or the air conditioner needs to be cooled is called that the electric automobile has a cooling requirement. In order to meet the heating requirement and the refrigerating requirement of the electric automobile, the distributable electric energy of the electric automobile is dynamically regulated through a thermal management system, so that heat required by heating is provided for a power battery and/or an air conditioner under the condition that the electric automobile has the heating requirement; and in the case that the electric automobile has a refrigeration requirement, providing the power battery and/or the air conditioner with a refrigerant required for refrigeration.
From the perspective of thermal management, in the case of an electric vehicle having both a heating requirement and a cooling requirement, if the allocable maximum power of the electric vehicle cannot simultaneously satisfy the heating power required to achieve the heating requirement and the cooling power required to achieve the cooling requirement, the expected heating effect or cooling effect cannot be achieved. In order to alleviate the phenomenon, the embodiment of the application provides a control method for a vehicle, which is suitable for a whole vehicle controller of an electric vehicle, and can reasonably distribute heating power and refrigerating power according to the degree of the electric vehicle on the heating requirement or the refrigerating requirement under the current working condition under the condition that the electric vehicle has both the heating requirement and the refrigerating requirement.
Fig. 1 is a flowchart of a vehicle control method according to an embodiment of the present application, where, as shown in fig. 1, the method includes:
S1, determining the current working condition of a vehicle according to the use state of the vehicle;
S2, determining heating power, cooling power and distributable maximum power required by the vehicle under the current working condition;
s3, when the distributable maximum power is smaller than the sum of heating power and refrigerating power, determining the priority of the heating requirement and the refrigerating requirement of the vehicle under the current working condition;
S4, sequentially distributing power for the heating requirement and the refrigeration requirement according to the priorities of the heating requirement and the refrigeration requirement.
In the embodiment of the application, the current working condition of the electric automobile refers to a state of the electric automobile in the using process, and the mode of determining the current working condition of the electric automobile is not limited in the embodiment of the application. In an alternative embodiment, the current working condition of the electric vehicle may be determined according to the charging mode of the electric vehicle or the starting state of the vehicle. For example, determining whether the current working condition of the electric vehicle is a charging working condition by identifying a charging mode corresponding to a charging port of the electric vehicle; or acquiring the starting state of the vehicle from the driving system, and determining whether the current working condition of the electric automobile is a driving working condition.
For example, if the charging mode corresponding to the charging port of the electric vehicle is any one of the charging modes of the ac slow charge 8A, the ac slow charge 13A, the ac slow charge 32A and the dc charging mode, the current working condition of the electric vehicle is determined to be the charging working condition corresponding to the current charging mode. If the charging mode corresponding to the charging port of the electric automobile is the non-external charging mode, the electric automobile can be determined to be not charged currently, a vehicle starting state is obtained from a driving system of the electric automobile, and whether the vehicle starting state is a ready state or not is determined; if yes, determining the current working condition of the electric automobile as a running working condition; the vehicle start state is a ready state, which means a state that the electric vehicle is ready for running.
In another alternative embodiment, the current working condition of the electric automobile can be determined according to the working state of the vehicle component in the electric automobile; for example, for a range extender electric vehicle, the current working conditions of the electric vehicle can be divided into working conditions of the range extender and non-working conditions of the range extender according to the working state of the range extender.
In another alternative embodiment, the current working condition of the electric automobile can be determined according to the energy demand state of the vehicle component in the electric automobile; for example, the power battery and/or the air conditioner currently have a heating requirement, and the current working condition of the electric automobile can be called a heating working condition; for another example, the power battery and/or the air conditioner currently has a refrigeration requirement, and the current working condition of the electric automobile can be called a refrigeration working condition.
In another alternative embodiment, the thermal management system may provide different thermal management modes for the power cells based on the corresponding heating or cooling requirements of the power cells at different temperatures, based on which the current operating conditions of the electric vehicle may also be determined from the thermal management mode perspective. For example, when the temperature of the power battery is in the range of 20-35 ℃, the charging and discharging capacity and the service life of the power battery are optimal, and the power battery does not need to be heated or refrigerated at the moment; alternatively, the condition where the temperature of the power cell is in the temperature range of 20 ℃ to 35 ℃ may be referred to as a no heating/cooling condition.
For example, when the temperature of the power battery is within the range of-10 ℃ to 20 ℃, the service life of the power battery is not affected, but the charge and discharge capacity of the power battery is poor, and the power battery needs to be heated to a light degree; alternatively, the condition of the power battery corresponding to the temperature of-10 ℃ to 20 ℃ can be called a weak heating condition. For another example, when the temperature of the power battery is in the range of 35-45 ℃, the charging and discharging capacity and the service life of the power battery are slightly influenced, and the power battery needs to be refrigerated to a light degree; alternatively, the condition of the power battery corresponding to the temperature of 35-45 ℃ can be called a weak refrigeration condition.
For example, when the temperature of the power battery is within the range of minus 30 ℃ to minus 10 ℃, the service life of the power battery is not affected, but the charging and discharging capacities of the power battery are poor, overcharge is easy to occur, and the power battery needs to be heated to a high degree; alternatively, the condition of the power battery corresponding to the temperature range of-30 ℃ to-10 ℃ can be called a strong heating condition. For example, when the temperature of the power battery is within the range of 45-55 ℃, the service life of the power battery is shortened, the charging and discharging capability is poor, the electric automobile is easy to claudication, and the power battery needs to be refrigerated to a stronger degree; alternatively, the condition of the power battery corresponding to the temperature of 45-55 ℃ can be called forced cooling condition.
In another optional embodiment, the current working condition of the electric vehicle may be determined according to a State of Charge (SOC) of the power battery, that is, a remaining power, and optionally, the SOC range of the electric vehicle may be divided according to a range capability of the electric vehicle. For example, the division is performed according to SOC < 20% and SOC of 20% +.; the SOC is less than 20% and the driving range of the electric automobile is lower, the working condition corresponding to the SOC range can be called as a low-energy working condition, the SOC is 20% or less and the driving range of the electric automobile is normal, and the working condition corresponding to the SOC range can be called as a normal working condition.
It should be noted that the working conditions of the electric vehicle are only exemplary, and are not limited thereto. In addition, various working conditions of the electric automobile are not independent, and the electric automobile can have various working conditions at the same time within the same time range. For example, the electric vehicle may have a heating condition or a cooling condition at the same time under a charging condition or a driving condition.
Under the condition of determining the current working condition of the electric automobile, the heating power required by the electric automobile for realizing the heating requirement and the refrigerating power required by the electric automobile for realizing the refrigerating requirement under the current working condition can be identified from the thermal management angle, and the allocable maximum power of the electric automobile is determined according to the current working condition; the maximum power that the electric vehicle can distribute refers to the maximum output power that the electric vehicle can provide.
Optionally, if the current working condition of the electric vehicle is a charging working condition, the current distributable maximum power of the electric vehicle is the maximum power which can be provided by the charging pile; if the current working condition of the electric vehicle is a driving working condition, and the electric vehicle is a pure electric vehicle, the current distributable maximum power of the electric vehicle is the maximum output power of the power battery; in the case that the electric vehicle is a range-extended electric vehicle, the current maximum power that can be allocated to the electric vehicle is determined by the power battery and the range extender. Judging whether the range extender works or not from the angle of working conditions of the range extender when determining the maximum power which can be distributed by the electric automobile, and if the electric automobile is in a working condition that the range extender does not work, obtaining the maximum output power of the power battery as the maximum power which can be distributed currently by the electric automobile; and if the electric automobile is under the working condition of the range extender, the maximum output total power of the power battery and the range extender is the maximum power which can be distributed by the electric automobile at present.
Further, whether the heating requirement and the refrigerating requirement of the electric automobile can be simultaneously met is determined according to the distributable maximum power of the electric automobile. In general, in the case of an electric vehicle having a heating requirement, a vehicle component that plays a major role is a water heater in a heating circuit, and the circulating water in the heating circuit is heated by the water heater, so that a required amount of heat can be provided for the electric vehicle to achieve the heating requirement. Therefore, when the heating power required by the electric automobile under the current working condition is identified, the power required by the water heater in the heating loop can be identified, and the power is used as the heating power required by the electric automobile under the current working condition. In the case of an electric vehicle having a refrigeration requirement, the vehicle component that plays a major role is the compressor in the refrigeration circuit, by means of which the electric vehicle can be provided with the required refrigerant for achieving the refrigeration requirement. Therefore, when the refrigeration power required by the electric automobile under the current working condition is identified, the power required by the compressor in the refrigeration loop can be identified, and the power is used as the refrigeration power required by the electric automobile under the current working condition.
Further, according to the maximum power which can be distributed by the electric automobile and the heating power required by the heating requirement and/or the refrigerating power required by the refrigerating requirement, under the condition that the maximum power which can be distributed by the electric automobile can not simultaneously meet the heating requirement and the refrigerating requirement of the electric automobile, the heating power and the refrigerating power can be reasonably distributed according to the requirement degree of the electric automobile on the heating requirement and the refrigerating requirement under the current working condition. In the embodiment of the application, the vehicle performance of the electric vehicle can be divided into power performance, thermal management performance, cockpit comfort performance, economic performance, power battery service life and charging performance from the aspects of power performance, thermal management performance, cockpit comfort performance, economic performance, power battery service life and charging capability of the electric vehicle and the like. It should be noted that these vehicle performances are not related in any case, and the vehicle performances related to the electric vehicle under different working conditions may be different, and may be one or more. Further, the extent to which an electric vehicle may be required for the same vehicle performance may vary from one operating condition to another.
For example, in the case of an electric vehicle in a charging condition and with an external temperature being too low, the temperature being too low has an influence on the service performance of the power battery, and the power battery has a heating requirement from the viewpoint of improving the charging performance of the power battery; in addition, in order to ensure comfort in the cockpit in a low temperature environment, the air conditioner also has a heating requirement from the viewpoint of cockpit comfort performance. But it is more important to ensure the service performance of the power battery than the comfort performance of the cockpit, so that the thermal management performance should be preferentially ensured, and the comfort performance of the cockpit should be considered.
For example, in summer and under the condition of the running condition of the electric automobile, if the current temperature of the power battery is the proper temperature for the power battery to work or the external temperature has little influence on the service performance of the power battery. From the standpoint of thermal management performance, the power cell does not have a heating or cooling requirement, or the heating or cooling requirement of the power cell is weaker. Under the driving condition of the electric automobile, a user can sit in the cockpit, and in order to ensure the comfort in the cockpit in hot summer, the air conditioner has refrigeration requirements from the viewpoint of the comfort performance of the cockpit, so the comfort performance of the cockpit should be preferentially ensured.
Based on the above, the embodiment of the application can predefine the priority among the vehicle performances under different working conditions of the electric vehicle, and under the condition of determining the current working condition of the electric vehicle, the priority of the heating requirement and the cooling requirement of the electric vehicle under the current working condition can be determined by combining the predefine priority of the vehicle performances under the working conditions of the electric vehicle, so that the power is sequentially distributed for each vehicle component for realizing the heating requirement and the cooling requirement from the distributable maximum power according to the priority of the heating requirement and the cooling requirement.
In an alternative embodiment, in case the priority of the heating demand is higher than the priority of the cooling demand, the water heater is preferentially allocated with the required heating power p1 from the allocatable maximum power p, and the compressor is allocated with the required cooling power p3 from the remaining allocatable power p 2; i.e. p2=p-p 1, p3=p2. For example, in the case where the priority of the heating demand of the electric vehicle is higher than the priority of the cooling demand, if the maximum power that the electric vehicle can currently distribute is 5000W, the heating power required for the water heater is 4000W, and the cooling power required for the compressor is 2000W. Based on the above, it can be determined that the allocable maximum power of the electric vehicle cannot meet the heating requirement and the cooling requirement at the same time, 4000W is preferentially allocated to the water heater from 5000W of the allocable maximum power as heating power, and further, the remaining 1000W is allocated to the compressor as cooling power, so as to preferentially meet the heating requirement.
In a further alternative embodiment, in case the priority of the cooling demand is higher than the priority of the heating demand, the compressor is preferentially allocated the required cooling power p3 from the allocatable maximum power p, and the water heater is allocated the required heating power p1 from the remaining allocatable power p 2; i.e. p2=p-p 3, p1=p2. For example, in the case where the priority of the cooling demand of the electric vehicle is higher than the priority of the heating demand, if the maximum power that the electric vehicle can currently distribute is 5000W, the cooling power required for the compressor is 4000W, and the heating power required for the water heater is 2000W. Based on the above, it can be determined that the allocable maximum power of the electric vehicle cannot meet the heating requirement and the cooling requirement at the same time, 4000W is preferentially allocated to the compressor from 5000W of the allocable maximum power as cooling power, and further, the remaining 1000W is allocated to the water heater as heating power to preferentially meet the cooling requirement.
Further optionally, in the case that the current working condition of the electric automobile is a charging working condition, in order to meet the basic working requirement of the power battery, before the heating power and the refrigerating power are allocated according to the priority of the heating requirement and the refrigerating requirement, the basic charging power p4 required by the power battery can be allocated preferentially from the allocatable maximum power p; further, the power p1 and p3 can be sequentially allocated from the remaining allocable power p2 for the water heater and the compressor for realizing the heating and cooling demands according to the priorities of the heating demands and the cooling demands; p2=p4, when the priority of the heating demand is higher than the priority of the cooling demand, p3=p2-p1, and when the priority of the cooling demand is higher than the priority of the heating demand, p1=p2-p3. Alternatively, the basic charging power of the power battery may be a preset prescribed power value, for example, 500W, or may be automatically adjusted according to the maximum charging capability corresponding to the charging pile, which is not limited herein.
For example, an electric vehicle may have a higher priority for cooling than heating under certain charging conditions, and the electric vehicle may currently be capable of distributing a maximum power of 5000W. If the basic charging power required by the power battery is 1000W, the refrigerating power required by the compressor is 3000W, the heating power required by the water heater is 2000W, and it can be determined that the allocable maximum power of the electric automobile cannot meet the heating requirement and the refrigerating requirement at the same time, then 1000W is preferentially allocated to the power battery from 5000W as the basic charging power, 3000W is allocated to the compressor from the rest 4000W as the refrigerating power, and further the rest 1000W is allocated to the water heater as the heating power, so as to preferentially meet the basic working requirement and the refrigerating requirement of the power battery.
It should be noted that the above embodiments are merely exemplary, and are not limited thereto, and the above-described manner of distributing power is still applicable in the case where the electric vehicle has only a heating requirement or a cooling requirement. Further alternatively, the embodiments of the present application may also be applied to other power distribution scenarios, and are not limited to the distribution of heating power and cooling power. For example, power can be distributed to the engine and the generator from the perspective of power performance or economic performance, and the specific implementation situation can be determined according to actual requirements.
In the embodiment of the application, the heating power and the refrigerating power required by the electric automobile and the distributable maximum power of the electric automobile can be determined according to the current working condition of the electric automobile; under the condition that the maximum power which can be distributed by the electric automobile can not simultaneously meet the heating requirement and the refrigeration requirement, the priority of the heating requirement and the refrigeration requirement under the current working condition can be confirmed according to the pre-defined heating requirement and refrigeration duration priority under each working condition, and the required power is distributed for each vehicle part for realizing the heating requirement and the refrigeration requirement according to the priority in sequence, so that the available power is reasonably distributed under the condition of meeting the heating requirement and the refrigeration requirement priority, and the available electric energy of the electric automobile is managed according to the requirement.
